Abstract
An information transmission method for a random access procedure and a terminal are disclosed. The method includes: obtaining a mapping relationship between interlaces of physical random access channel PRACH resources and physical uplink shared channel PUSCH resources, where the interlace includes at least one PRACH resource unit; and sending a random access message on a random access resource according to the mapping relationship, where the random access resource includes the PUSCH resources and the PRACH resources.
Claims20
A terminal, comprising a chip which, when running on the terminal, cause the terminal to perform:
- obtaining a mapping relationship between at least one physical random access channel (PRACH) resource unit of PRACH resources and physical uplink shared channel (PUSCH) resources;
- and
- sending a random access message on a random access resource according to the mapping relationship, wherein the random access resource comprises the PUSCH resources and the PRACH resources;
- wherein the mapping relationship comprises:
- the at least one PRACH resource unit are mapped to the PUSCH resources in an ascending order of random access preamble indexes in one RO;
- or,
- the at least one PRACH resource unit are mapped to the PUSCH resources in an ascending order of DMRS port indexes in one PUO.
An information transmission method for a random access procedure, performed by a terminal, wherein the method comprises:
- obtaining a mapping relationship between at least one physical random access channel (PRACH) resource unit of PRACH resources and physical uplink shared channel (PUSCH) resources;
- and
- sending a random access message on a random access resource according to the mapping relationship, wherein the random access resource comprises the PUSCH resources and the PRACH resources;
- wherein the mapping relationship comprises:
- the at least one PRACH resource unit are mapped to the PUSCH resources in an ascending order of random access preamble indexes in one RO;
- or,
- the at least one PRACH resource unit are mapped to the PUSCH resources in an ascending order of DMRS port indexes in one PUO.
A non-transitory computer-readable storage medium, wherein the non-transitory computer-readable storage medium stores a computer program, and when the computer program is executed by a processor, an information transmission method for a random access procedure is implemented, and the method comprises:
- obtaining a mapping relationship between at least one physical random access channel (PRACH) resource unit of PRACH resources and physical uplink shared channel (PUSCH) resources;
- and
- sending a random access message on a random access resource according to the mapping relationship, wherein the random access resource comprises the PUSCH resources and the PRACH resources;
- wherein the mapping relationship comprises:
- the at least one PRACH resource unit are mapped to the PUSCH resources in an ascending order of random access preamble indexes in one RO;
- or,
- the at least one PRACH resource unit are mapped to the PUSCH resources in an ascending order of DMRS port indexes in one PUO.
